Nucleation of superconductivity in finite anisotropic superconductors and the evolution of surface superconductivity toward the bulk mixed state
(American Physical Society, 2002-02-14)
In anisotropic superconductors having an arbitrary orientation of the sample surface relative to the crystal principal axes, the surface critical field H-c3 is less than 1.695H(c2) unless the field is situated along one ...
semiclassical wave-packet scattering in one and two dimensions
(AIP Publishing, 2004-11)
We prove that under short range potentials a semiclassical wave packet's propagation is accurate for infinite times in the (h) over bar -->0 limit. (C) 2004 American Institute of Physics.
Numerical simulation of drop retraction after a strain jump
(American Physical Society, 2009-04)
A spherical drop of one liquid suspended in another is subjected to an instantaneous initial shear. We simulate the retraction of the drop to its spherical equilibrium and compare the results with recent experiments. In ...
resonances in a box
(AIP Publishing, 2000-01)
We investigate a numerical method for studying resonances in quantum mechanics. We prove rigorously that this method yields accurate approximations to resonance energies and widths for shape resonances in the semiclassical ...
large eddy simulation of turbulent channel flows by the rational large eddy simulation model
(AIP Publishing, 2003-10)
The rational large eddy simulation (RLES) model is applied to turbulent channel flows. This approximate deconvolution model is based on a rational (subdiagonal Pade) approximation of the Fourier transform of the Gaussian ...
capillary-gravity wave drag
(AIP Publishing, 2001-08)
Drag due to the production of capillary-gravity waves is calculated for an object moving along the surface of a liquid. Both two and three dimensional objects, moving at large Froude and Weber numbers, are treated. (C) ...
inertia-induced breakup of highly viscous drops subjected to simple shear
(AIP Publishing, 2003-05)
We investigate the inertia-driven breakup of viscous drops suspended in a less viscous liquid under simple shear. For Stokes flow, it is known that there is a critical value of the viscosity ratio, beyond which breakup ...
Small-energy asymptotics of the scattering matrix for the matrix Schrodinger equation on the line
(AIP Publishing, 2001-10)
The one-dimensional matrix Schrodinger equation is considered when the matrix potential is self-adjoint with entries that are integrable and have finite first moments. The small-energy asymptotics of the scattering ...
experimental observation and matching numerical simulation for the deformation and breakup of immiscible drops in oscillatory shear
(AIP Publishing, 2002-09)
This paper describes experimental results on the way immiscible drops of a Newtonian fluid can deform and breakup when subject to oscillatory shear deformation. The paper also reports a matching three-dimensional numerical ...
A finite element splitting extrapolation for second order hyperbolic equations
(Siam Publications, 2009)
Splitting extrapolation is an efficient technique for solving large scale scientific and engineering problems in parallel. This article discusses a finite element splitting extrapolation for second order hyperbolic equations ...
